Project Title Pictobot

Indoor painting is an integral part of construction of large industrial buildings. Current methods of indoor painting consist of using 2 painters and a forklift which is slow and time consuming. It is also dangerous and poses dangers to painters such as falling from a height and inhalation of paint fumes. With these challenges in mind, Pictobot was created by Nanyang Technological University (NTU) and JTC. The Indoor painting robot boasts the ability to spray paint walls 20% faster than conventional methods and consists of scanners to scan wall surfaces. However, the scanners used are limited in both their accuracy and efficiency. Firstly, the scanners used are 2 Dimensional scanners (2D) and not 3 Dimensional (3D) ones. This greatly hinders the ability of the scanners to scan wall surfaces accurately as 2D scanning cannot pick up minute details and is much vaguer. The scanners also move in increments over 160 degrees to scan wall surfaces. After every increment, it will stop to verify if it is in the correct position before moving again. Valuable time is used up unnecessarily in this process as the number of steps taken by the scanner can be greatly reduced, undermining the very goal for which the Pictobot was created which is to increase efficiency in Indoor scanning. There is also the concern of decreased accuracy if the number of steps is reduced too much since the image produced will be of a low resolution. Hence, this project aims to resolve the problem of accuracy by incorporating 3D scanning into the Pictobot and the problem of efficiency by determining the optimal number of steps for the scanner to move without a significant decrease in accuracy.   (280 words)
